Possibly copper seals/washers on the injectors. If these are leaking the return fuel flow will carry gas bubbles from exhaust gases.

A leak in fuel lines / filters will not induce gases - these lines are under pressure - they blow not suck !

It could of course simply be a case that your pump is on its way out
